anyone here crochet? I've been learning thru youtube videos. I'm working on a flower granny square afghan right now. The flowers are different colors with a dark purple center and a white background. For my next project I think I want to do something bright like this http://attic24.typepad.com/weblog/hexagon-howto.html. I love the hexagon look. Question is, where do I find such bright colors? Joanne's selection the last time I was there was mostly boring colors. Michaels seemed the same way. Also, is acrylic better than cotton, or vice versa?
